Oddly, none of that brought me any closer to understanding why he's crossing the picket line. I can visualize a prof on the other side of the line writing the same thing. (hopefully a prof somewhat more fond of brevity)
Yeah! Math Prof has definitely chosen a side. He obscures that move in a fluff of "politics is complex, decisions are difficult." But politics is everything, and he's engaged in politics knee-deep while pretending not to be. "All I care about is education" calmly states the unwitting Math Prof as education is destroyed to become a hollow commodity for those who can afford it. He's obscuring his politics and hiding that fact that he wants a continuation of the current state of things.
